TO ALL WHOM IT MY CONCERN: A

Be it known that I, JAMES GILBERT, of Wyalusing, in the county ofGrant, and State ofV Wisconsin, have invented a new'and useful Improvement in Corn-Planter: and I do hereby declare that the following is e full, clear, und exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompenying'drawings, forming part of this specification, in which-d Figure l is a top view of my improved corn-planter, the cover beingremoved.v

Figure 2 is a detuil end view of the same, parts being broken away.

Figure 3 is a. detail sectioncliview ofthe same, teken through the line y y, fig. l.

Eigure 4 is ai detail sectional view of the same, taken through the line x zu, iig. l.

Similar letters of reference indicate clorresponding parts.

My invention ,has for its object to furnish au improvedcormplanter, which shall be simple in construction, und effective, reliable, and accurate irl-operation; and it consists in the construction, combination, and arrangement of the various parts, as hereinafter more fully described.

A is the frame of the machine, to the forward side of which are attached the hounds a', tn which the tongue B is attached, and to the ends of which are attached the axles C, upon which therwheel's D work. E is the box, which contains the dropping-devices, the bottom, front side, and ends of which are permanently attached to the frame' A, but the rearv side, to whchthe cover is hinged, is removable, being held in place by thehooks F. G are the seed-boxes or hoppers, theforward sides of which are secured to-the forward side of the box E, and the bottoms of which `fit and rest. upon the droppingcyliuder H, which passesA longitudinally through, and the ends of which rest and work in bearings in the ends of the box E. In the parts ofthe cylinder H, upon which the seed-boxes G rest, are formed holes or recesses, of such a size as to'contciu the desired amount of seed for each hill. The seed passes into the recesses ofthe cylinder H, through holes in the bottom of the seed-boiresG, and it is discharged from the cylinder H into hopper-shaped discharging-orices in the bottom of the box E. The escape ofthe seed fromthe seed-boxes G is prevented, when desired, by sliding gates I, which work in slots in the bottoms of said seed-boxes, and the ends of which pass out through the front side of the box E, so that they may be conveniently operated by the driver. To one end of the cylinder His attached a gear-wheel, J, the teeth of which mesh into the teeth of the gear-wheel K, attached to the inner end of the hub of one of the wheelsD, so thet the said cylinder H may be operated to drop the seed by the advolnce of une machine. L is e. lever, one end of which is pivoted to the end of the box E, and which is connected with .the cylinder H, as shown in iig. 2, so that by operating the said lever, the said cylinder H may be thrown into and out of gear with the wheel D, when desired. Mare thefts4 passing through and working in holes in the sides of the seedboxes G, and which have short downwardly-projecting arms or stirrers N attached to their middle parts, bythe vibration of which the seed is agitated ortirred to prevent its clogging. .To one end of the shafts M is attached en elbow-lever, O, one endr of which projects downward and rests gainst e shoulder or projection of the support, to which the end of the shaft M is pivoted. The other arm ofthe elbow-lever O projects horizontally, and has a. weight, P, suspended from its outer end. To the cylinder H, beneath the elbow-levers 0, are attached pro4 jecting'arms R, whichpas the seid cylinder revolves, strikes against the downwardly-projecting erms of the` levers .0, and raise them, the weights P bringing them back 'to their former position as soon as released from projections E, thus communicating s. re'cipro'ating or vibrating motion to the stirrers N. S are the ploughL standurdsto the lower ends of .ivhichthe ploughs are attached, und the upper ends cf which ere attached to rollers U, the journals of which revolve in bearings in the framelA of themachine. 'lhe lower parte of th'e standards S ore connected with the lower ends of the levers V by theV connecting-rods or chains W. lThe levers V are pivotcd to the upper part of theforward side of the front cross-bar of the frame A, so that the draught# strain upon the ploughs may be sustained by the frame of the machine. The upper ends of the levers V pro-A jcct'ubcve the frame A, so that they may be easily reached und operated by the driver to raise the ploughs away from the ground when required. X are spduts or tubes attached to the rear side of the standards yS, in such positions that when the plough-standards are in their workingpositions the said tubes or spouts miiy receive the seed and 'conduct it to the ground just inthe rear of the ploughs Y are smell Vshaped, hnrrows, the forward ends of which are connected by short chains enjoint-ed conneetingu'ods Z to the standsrdsS. The

harrows Y are still furthersustn'ned and kept 'in .their proper relative positions while being operated, by the shortl chains or connecting-rods A', the lower ends-of` which are connected tothe lmiddle part of the harrows, andthe upper 'ends of whichare connscted'tothe rear cross-bar of the frame '.A, -asshown in 6g. 4. this construction the seed is partially covered the inflow of the-soil in' the rear of the ploughs T. The Barrows Y cornplete the covering und smooth off thcV surfacc'of the ground. The levers Y inny'bel heldin plnce ywhen .drawn back to raise'the ploughs and'hurows away lfrom the ground by the'hooks B', attach-ed. to the framel A,

as shown in iig. 1. The tongue Bl is passed through a keeper upon the lower -side of' the-.hounds a', and is secured in place by the bolt C phasing down 'through the centrul'bar of said hounds, :ind through the said tongue. The lower end o1" the bolt C' passes through nholo in the forward arm of the three-rmed bar or plato D', to the end of the rearwardly-projecting arlns of which arel connected the forward ends o f thedraught-rodsI E', which pass back through the lower ends of the downwardlyfprojecting brackets 'or supports'F, and the rear ends of which aresecured to the rear part of the frame A.- By this arr'nngement the line of draughtl is so much 'lowered that the downward strain is removed from the-necks'of the'horses, enablingthem todo their work with 'much greater ense and comfort.

I claim as new, and desire to secure 'by Letters Patent-f-V *1e v.Connecting the plough-standards S .to the frame A by means of the rollers U, suhstsntially as herein show n and described, and for the purpose 'set forth. l

2. .The combination of' the.levers V andy connecting-rods or chains W with the plou'glx-stapdardls S und frame A, for raising, lowering, -and supporting said standards, substantially es herein shown and described.

8. The combination-of the weighted elbow-lever O and shaft M, havingarms or stirrers N attached toit,

with the seed-box' G, nd with the projections R formed uponor attached to the dropping-'cylinder-H, neuheitentially as herein shownV and described, and lfor the purpose set forth. 4

4. The eombination'of the harrows Y with the plough-stnndards -S and frame A,'substantially as herein shown and described, andfor the purpose set forth. A A

5. vApplying the-draught below the horizontal plnneoil` 'the iframe A, substantially 'as herein shown and described, und for the purpose set forth.
